JEROME F. MCCALL, .or PHILADELPHIA, PENNSYLVANIA.

. Bc it knownv thatI, JEROME F. MCGALI'.,

' a citizenof the United States, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented a" newan'd-useful Improvement in Boxe s ofwhich the followin is a. specification;V

which can be easily .folded for use, and

which is strong and stiff and well stayed when arranged in position foruse.4

The invention is Vcapable of many embodi- 4ments 4among which I- have chosen several which I believe will be suicient for explanation and have illustrated them in the accompanying drawingsinwhich- Figure 1, is a top or plan view lof a blank which can be folded intoa boxmember embodying features of the invention. Fig. 2,

is a; plan view illustrating the operation of folding the blank. Fig. 3, is a side view illustrating the samething. Fig. 4,'is a cross sectional view somewhat m perspective and withparts broken away, illustrating a box member embodying features of the invention. Fig.,5, 'is a sectional View taken on the line 5 5, of Fig. 4.. Fig. 6, is a view somewhat similar to Fig. 2, and illustrating the employment of staples. Fig. 7, is a view of a part of a blank which when folded constitutes a box member embodying a modification of the invention. Fig. 8, is

4a cross-sectional view 'somewhat in perspec? tive villustrating the box membermade from the blank' shown in Fig. 7, but not quite completed. Fig. 9, is a view similar to Fig. 8, with parts brokenfaway, showing the box member. completely assembled. Fig. 10, is a view of a blank which, when folded, constitutes a box member embodying another modification ofthe invention. Fig. 11, is a View showing-the blank of Fig. 10, partly;

folded, and Fig. 12, is a longitudinal section showing a box member made from the blank of Fig. 10.

I between the parts of the fold. .On the ex- By box member is meant either a lid or a tray the depth or height of which may be increased-or diminished.

"The end"1,is provided with an inturned fold 2. The side 3, is provided with an extension 4,.Figs. 1-6, 4a, Figs. 7 -9,and 4c, Figs. 10-12, and this extension is arranged a tension thereisaninwardffi fFigs, 14,9, the extension fis ldouble'c'llbiitis merely turned isn betweenfthe sirable to use' staples or-fasten-ingssatfithe 1 doubled f, andV 'creased' part 'f of the. extension andzth'ese are indicated at?, in Fig;y 6". The flaps' may be variously.arangedlortli exilfifgs. Y 10-112, vthe extensosagaienotcreseerfaad Th .principal object of the inventionis tol i p rovidefa` folding box which can be made vcomplete from la single blank and is th ere.` fore comparativelyy inexpensive to make,-

tensions 'and accordingito 'theirarrangement?i()v on ythe extensions? their` positioninf thefb'ox member may be somewhat varied; but in every case they project inward substantially parallel with the inner face of the body of the box member, sometimes being in contact with that face, Figs. 1w6 and 10-12, and

sometimes being above that face, Figs. 7-9. The flaps 5, Figs. 1-6,'are prolongations of the sides. This is true also of the flaps 5a in Figs. '7-9. In Figs. 1042, the flapsc project laterally from the extensions or sides.

In Figs. 1-6 and 1042, the flaps extend to the bottom of the box member as do also the folds2, and this construction is suitable for comparatively shallow box members.

In the construction shown in Figs. 7 -9, the fold 2, does not extend to the bottom of the box member and the inward iap 5a is not near the bottom of the box member butpasses through the creased or doubled portion 6, so that its inwardly 'projecting end can engage the fold. The construction last described is suitable for deep trays such as hat boxes because the saving of material effected by shortening up the fold 2, may be substantial.

The extension, the flap, and the inner part of the fold, as has been said, engage one another. For Vthis purpose tongues S, and 8, areshown in Figs. 2 and 11, on the inner part of the fold. Tongue receiving openings 9, 9, and 9c, Figs. 2, 8 and 11, are shown in the flaps. j,.;

The engagement of the inner-part of the fold with the flap when the parte are combined and arranged as described provides an eiicient stay which imparts to the box memf ber firmness and rigidity. Since the entire box member can be madein one piece it follows that its production is comparatively inexpensive.

To fold the blank in Figs. 1G, the sides ioo are turned into erect position, the extensions are turned in onto the sides, the sidesl are folded along the crease 6, thus bringing the end into erect position With the flaps 5, eX tending inward in contact with the inner face of the box member; The fold 2is then turned in and its tongues 8, are made to engage the openings inthe iiaps 5, and so the box member is-locked. In Figs. 7-9, the operation is the same except that lthe flaps 5a, pass V through the parts but they extend arallel with the inner face of the. box mein er and inward. In Figs. 10-12, the operation is the same as described in connection with Figs. 1-6, except that the creasingat the corners is omitted. The iaps, project inward in contact with the inner face of the box member.

That I claim is:

1. In a box member the combination of ends and sides in folded relation at the corners, Van inturned fold on the end, and a. flap i `the inner face of the body of the box inem-4 ber and engaging the inner part of the inturned end fold and constituting therewith a-lock.

2. In a box member the combination of an end having an inturned fold, and aside passing back of said fold and having an integral flap extending inward past the fold and arranged substantially parallel With and free from the inner face of the body of the box member and engaging the inner part of the inturned fold to constitute a lock.
